Abstract: A distributed biometric identification system incorporates stand-alone workstations. The system generally includes a plurality of stand-alone workstations capable of communicating with a central server remotely located from the workstations. The workstations receive input biometric data, such as fingerprint and photographic data, and compares that data to biometric data stored in the workstation. The workstation compares the input biometric data with stored biometric data to determine whether any of the stored biometric data matches the input biometric data. The results of the comparison are provided to the workstation screen. Workstation mobility is improved by housing the workstation in a self-contained, compartmentalized carrying case.      Workstation mobility may be even further enhanced by housing the workstation in a so-called lunchbox configuration having a main body, a front panel hinged to the main body, and a back panel hinged to the main body. The front and back panels each have a stowed position adjacent the main body, and a deployed position away from the main body. When the panels are in their stowed positions, the workstation (i.e., main body, front panel, and back panel) is a compact, portable unit.

Abstract: An apparatus for augmenting ventilation of a patient (100) and monitoring the patient's breathing patterns uses a transtracheal catheter (10). A substantially constant flow of oxygen/air is supplied through one of the lumens (12) of the transtracheal catheter (10) into the patient's tranchea (101) to augment the patient's spontaeous breathing.      A respiration sensor (80, 82, 85 or 87) measures a predetermined physical property (e.g., pressure or flow rate) related to the patient's respiration at the distal end (17) of the transtracheal catheter (10). This data is recorded to monitor the patient's respiration patterns over time for subsequent analysis. The respiration data can be recorded on a strip chart or stored in digital form for transmission by modem or removable data storage media to a remote facility for analysis. A capnometer (87) can be connected to one of the transtracheal catheter lumens (16) to measure the carbon dioxide concentration of the air exhaled by the patient (100). The distal end of the transtracheal catheter (10) can also be equipped with an oximetry probe (85) that contacts the lining of the patient's trachea (101) to measure blood oxygen saturation. The oximetry data is recorded concurrently with the respiration data and used for diagnosis and monitoring of sleep disorders, such as sleep apnea and hypopnea.

Title: Method for producing 1,4-butanediol
Inventor: RAHN RALF-THOMAS
IPC: C07D307/32
Filed: 1999-04-16
Granted: 2009-03-24
Abstract: The invention relates to a method for producing 1,4-butanediol and possibly .gamma.-butyrolactone and tetrahydrofurane by oxidation of butane or benzol into a product flow containing maleic anhydride, absorption of maleic anhydride from the product flow by means of an inert, high-boiling solvent in an absorption stage, which yields a liquid absorption product, and esterification of said liquid absorption product with a C1-C5 esterification alcohol in an esterification step, yielding an esterification product containing the corresponding diester and high-boiling inert solvent. This is followed by hydrogenation of the esterification product, which results in an hydrogenation product containing the products 1,4-butanediol and optionally .gamma.-butyrolactone and tetrahydrofurane as well as the esterification alcohol. The hydrogenation product is separated by distillation into the products and the esterification alcohol and the esterification alcohol is returned to the esterification zone. Prior to hydrogenation the esterification product i s separated by distillation under reduced pressured into the diester and the inert solvent, the inert solvent is returned to the absorption stage and the diester is hydrogenated in the liquid phase on a fixed-bed catalyst.

Abstract: A low bit-rate (192 kBits per second) transform encoder/decoder system (44.1 kHz or 48 kHz sampling rate) for high-quality music applications employs short time-domain sample blocks (128 samples/block) so that the system signal propagation delay is short enough for real-time aural feedback to a human operator. Carefully designed pairs of analysis/synthesis windows are used to achieve sufficient transform frequency selectivity despite the use of short sample blocks. A  synthesis window in the decoder has characteristics such that the product of its response and that of an analysis window in the encoder produces a composite response which sums to unity for two adjacent overlapped sample blocks. Adjacent time-domain signal samples blocks are overlapped and added to cancel the effects of the analysis and synthesis windows. A technique is provided for deriving suitable analysis/synthesis window pairs. In the encoder, a discrete transform having a function equivalent to the alternate application of a modified Discrete Cosine Transform and a modified Discrete Sine Transform according to the Time Domain Abasing Cancellation technique or, alternatively, a Discrete Fourier Transform is used to generate frequency-domain transform coefficients. The transform coefficients are nonuniformly quantized by assigning a fixed number of bits and a variable number of bits determined adaptively based on psychoacoustic masking. A technique is described for assigning the fixed bit and adaptive bit allocations. The transmission of side information regarding adaptively allocated bits is not required. Error codes and protected data may be scattered throughout formatted frame outputs from the encoder in order to reduce sensitivity to noise bursts.

The recessed portion has a rigid conical projection (18) centered therein which has an orifice (20) extending into a pump inlet (22). The gear pump further includes a fluid container (36) mounted above the recessed portion of the pump housing to form a fluid reservoir. The fluid reservoir has a discharge valve (52) that is opened by engagement with the conical projection within the recessed portion to provide fluid communication to the pump inlet. A static head in the fluid reservoir maintains the gear pump in a primed state. A fluid line (30) leading from the gear pump to a sprayer head has a discharge check valve (34) located therein.      The check valve has a cracking pressure higher than the static head of fluid so that fluid passes to the sprayer head only when the gear pump operates to increase pressure in the fluid line above the cracking pressure. There is also means for powering and operating the motor such that the gear pump provides a continuous flow of fluid to the sprayer head upon demand by a user.

Abstract: Personal care or cosmetic oil in water emulsions include an oil emulsifier and a combination of a Xanthan polysaccharide and a polyglucomannan polysaccharide to provide enhanced stability even at low emulsifier stabiliser levels. The emulsifier stabiliser system provides stable emulsions without dominating system rheology, particularly viscosity. Thus, the emulsions can have a low viscosity suitable for formulation as milks or thin lotions, or can be thickened, desirably by thickening agents other than the Xanthan and/or polyglucomannan, to provide emulsion creams or gels. This enables the system to be used very flexibly in end use applications. The emulsifier is desirably a non-ionic emulsifier and particularly is a combination of a low HLB and a high HLB emulsifier and can be formulated with conventional alcohol ethoxylate surfactants or from non-EO surfactants e.g. sucrose ester high HLB surfactants and citrate or sorbitan ester low HLB surfactants.
